In addition, the wake interaction of upstream blade row and the expansion wave at rotor exit also cause an unsteady force acting on the downstream rotor blade surface.

此外上游静子尾迹以及动叶尾缘出口膨胀波等也是产生转子叶片表面非定常力的因素。

Finally, Over-all loss coefficients in the cascade are obtained, considering effects of the shock wave passage and wake.

最后，连同通道区和尾迹区一起，求得了包括冲波影响的叶栅的总损失系数。

My surfboard was quickly ripped out from underneath me, its leash yanking me into the wave's violent washing-machine wake.
